https://en.wikipedia.org/wiki/Ringfort
In Irish language <https://en.wikipedia.org/wiki/Irish_language> sources they are known by a number of names: *ráth* (anglicised *rath*), *lios* (anglicised *lis*; cognate with Cornish <https://en.wikipedia.org/wiki/Cornish_language> *lis*),[2] <https://en.wikipedia.org/wiki/Ringfort#cite_note-Helsbury-2> *caiseal* (anglicised *cashel*), *cathair* (anglicised *caher* or *cahir*; cognate with Welsh <https://en.wikipedia.org/wiki/Welsh_language> *caer*, Cornish and Breton <https://en.wikipedia.org/wiki/Breton_language> *ker*) and *dún* (anglicised *dun* or *doon*; cognate with Welsh and Cornish *din*).[3] <https://en.wikipedia.org/wiki/Ringfort#cite_note-Edwards-3> The *ráth* and *lios* was an earthen ringfort; the *ráth* being the enclosing bank and the *lios* being the open space within.[4] <https://en.wikipedia.org/wiki/Ringfort#cite_note-Irish_countryside-4> The *caiseal* and *cathair* was a stone ringfort.[3] <https://en.wikipedia.org/wiki/Ringfort#cite_note-Edwards-3> The term *dún* was usually used for any stronghold of importance, which may or may not be ring-shaped.[3] <https://en.wikipedia.org/wiki/Ringfort#cite_note-Edwards-3> In Ireland, over 40,000 sites have been identified as ringforts and it is thought that at least 50,000 ringforts existed on the island.[5] <https://en.wikipedia.org/wiki/Ringfort#cite_note-New_History,_550-5> They are common throughout the country, with a mean density of just over one ringfort within any area of 2 km2 (0.8 sq mi). It is likely that many have been destroyed by farming and urbanisation. However, many hitherto unknown ringforts have been found thanks to early Ordnance Survey <https://en.wikipedia.org/wiki/Ordnance_Survey> maps, aerial photography <https://en.wikipedia.org/wiki/Aerial_photography>, and the archaeological work that has accompanied road-building. Based on the above definitions, nodes should tagged with ring_fort but detailed mapping could use ráth and lios. I assume a relation tagged with ringfort would be appropriate for locations that have the ráth and lios mapped. Thoughts? Donal p.s. I have no other knowledge / opinion other that want I've read above. I do think they are cool and worth mapping. 50,000 is a lot of work!!!
